Abstract

A base of a three-point type folding bicycle saddle is made of ABS (acrylonitrile butadiene styrene) rigid engineering plastic, a layer of flexible polyurethane foam covers the base, and the outer surface is wrapped in leather or artificial leather; the saddle consists of a long-ladle-shaped folding front saddle cushion as well as left and right round saddle cushions, a ball head handle is installed on the rear side of the saddle, and the left and right saddle cushions can fluctuate leftwards and rightwards with forces when the forces are exerted by legs during riding, so that acting forces between the ischium of a rider and the saddle cushions are buffered, and pain caused by long-time sitting is alleviated; in addition, the folding front saddle cushion can hang forwards during riding after the ball head handle is pressed down, so that extrusion caused by the saddle cushions to pubes and prostate glands of men can be avoided effectively; when the front saddle cushion is pulled up, the front saddle cushion can be in a horizontal state; according to the saddle, structures of traditional bicycle saddles are changed, and the saddle is simple to manufacture and reliable to use.

Description

A kind of bikini folding bicycle seat

Technical field

The present invention relates to relate to a kind of outdoor exercises type bike saddle, the structure of innovating at its especially.

Background technology

At present, known outdoor exercises type bike saddle is all integral type, vehicle seat planar design is a triangle saddle, its bottom base is generally with the manufacture of ABS engineering plastics, on pedestal, cover one deck flexible polyurethane foam (artificial sponge) or silica gel, leather or artificial leather parcel for outside face, pedestal is supported by spring steel guide frame, relies on a steel pipe to be connected with bicycle rack with a secondary fastener.People ride and use this vehicle seat to there is no uncomfortable sensation the short time, will make people feel ischium and pubis generation pain, very uncomfortable but ride for a long time, especially the front portion of integrated vehicle seat is oppressed man's prostate, blood flow is obstructed, it is numb that perineum place feels, urine is all felt difficulty sometimes, therefore frequently must stand with one foot to the knee on tread plate, lift buttocks with compressing and the pain of releiving, this has just greatly affected riding speed and mind.On market, there is a kind of frontless vehicle seat recently, (so-called without nose vehicle seat) its similar roundlet stool, alleviate the hard pressed phenomenon of man's prostate, but owing to lacking vehicle seat front portion, user can lack sense of direction in the time that shank is exerted oneself, sit shakiness, feel to have the trend of downslide.

Summary of the invention

For above-mentioned defect and deficiency, the present invention according to human engineering, kinematics and machine manufacture principle design a kind of bikini folding bicycle seat, effectively solve these problems.

The technical solution adopted in the present invention is: the base material of vehicle seat adopts the manufacture of ABS hard plastics, on pedestal, cover the flexible polyurethane foam of one deck, leather or artificial leather parcel for outside face, it is by a folding front seat cushion of long wooden dipper shape and two circular left sides, right seat cushion forms, notch shape is made in described folding front seat cushion rear end, rely on two V-arrangement springs of its below and pass through a secondary two-thread screw, nut is hinged on a ratchet base, in the spiral coil of two described V-arrangement spring interludes, wearing in the spring clip slot that a pin rod is arranged on the rebasing portion of front stall, the epimere head of V-arrangement spring is fixed in the jack of the rebasing portion of front stall rear end, hypomere head is welded on the wheel hub of a single ratchet, described single ratchet is by a set of two-thread screw, nut is installed in a ratchet base and can rotates, described ratchet base is fixed on a front end above spring steel plate, the rear of this ratchet base is separately fixed wtih a gib head seat, a ball handle is arranged on therebetween and relies on a bearing pin to be through in gib head seat, this ball handle can swing up and down around bearing pin, described ball handle front end is a L shaped gib head, it is compressed and hooks single ratchet by a torque spring being enclosed within on bearing pin and makes front seat cushion maintenance level, in the time pressing ball handle, described L shaped gib head is just lifted and discharges single ratchet front seat cushion is forwards naturally drooped, described two are circular left, right seat cushion symmetry splits at front seat cushion axis rear side, their elevation profile profile is low above, high below, centre is depressed part, their below projection on assembling respectively a steel respectively use in flakes bolt and compression spring sheet fastened, compression spring sheet is withheld in the upper end of two pressure springs and is made it fixing, two described steel are middle in flakes to be joined and makes two circular left sides by a rivet pin hinge, right seat cushion can be along with fluctuation under the effect of external force, respectively withhold with a lower making leaf spring and respectively by another secondary bolt the lower end of two described pressure springs, nut and pad are fixed on spring steel plate, described spring steel plate below inclined weld a round steel pipe and is connected with the steel pipe frame of bicycle by fastener.

The invention has the beneficial effects as follows: medial recess and a left side of leaning forward, the weight that right seat cushion can cosily bear the pressure of buttocks and decompose part human body, when the middle shank of riding is exerted oneself, their energy left and right are along with fluctuation, cushion the application force of ischium and seat cushion, alleviate the pain of sitting, and folding front seat cushion can be pressed after ball handle to front hanging down in riding, and its rear end is made notch shape and has effectively been avoided seat cushion to pubis and the prostatic extruding of man, in the time that plate plays front seat cushion, can make it again to become horizontal, recover traditional use habit, it manufactures simple, use reliable and stable, change the structure of known bike saddle.
